A company produces two types of solar panels per year: x thousand of type A and y thousand of type B. The revenue and cost equations, in millions of dollars, for the year are given as follows. R(x,y) = 6x + 5y C(x,y)=x2 - 3xy + 9y2+ 14x-61y-7 Determine how many of each type of solar panel should be produced per year to maximize profit. The company will achieve a maximum profit by selling 5000 solar panels of type A and selling 7000 solar panels of type B. The maximum profit is $ 211 million
